Ultrasound‐Guided Hydrodilatation of the Shoulder Capsule at the Rotator Interval: Technical Tips and Tricks

Adhesive capsulitis and disorders of the intra‐articular portion of the long head of the biceps brachii tendon are common causes of shoulder pain. Sonographic findings, coupled with clinical evaluation and medical history, are paramount for prompt diagnosis. Herewith, either to precisely confirm the pain generator(s) or to appropriately treat relevant cases, ultrasound‐guided interventions are often required in daily clinical practice. Targeting the anatomical structures involved in the aforementioned pathological conditions, we briefly describe some technical tips and tricks as regards ultrasound‐guided hydrodilatation of the shoulder capsule at the rotator interval.
